Abstract

1,198,700. Casting composite articles; mouldlining materials. MITSUBISHI JUKOGYO K.K. 5 Oct., 1967, No. 45516/67. Heading B3F. In a method of producing a casting having a surface layer of different composition than the remainder, e.g. a corrosion resistant, an abrasion resistant, or an oxidation resistant layer, or a bearing surface, a mixture containing the powder of a metal or alloy is mixed with a binder and solvent and introduced into a mould 2 as a layer 4 on the surface of the mould cavity 3, molten metal is then poured into the cavity 3 either to alloy with the metal powder or to embed the particles in the cast metal. The mixture may contain an exothermic material and the binder may be a synthetic resin, paraffin, starch, or other organic binder, and the solvent may be methyl alcohol, acetone, or water. The powdered metal may include one or more of the elements Cr, Al, Ni, Si, Mn, C, N, Mo, W, Co, V, Zr, Nb and Pb, and the casting metal may be steel, cast iron, copper or copper alloy. A number of specific examples are described. The method may be used in connection with centrifugal casting, pressure casting with bottom pressure pouring, and vacuum casting. The mixture forming the layer 4 may also include oxides, carbides, nitrides, e.g. Al 2 O 3 , ZrO, Cr 2 O 3, TiC, AIN.
